▎ 摘　　要

NOVELTY - Composite material comprises multiple phases comprising at least one stiff phase (101) and a compliant phase (102), where the stiff phase and compliant phase are interpenetrating to form an interpenetrating network, and the network is bi-continuous, and the ratio of bulk moduli of the stiff phase to the compliant phase is 2. USE - Composite material for use in energy dissipation such as absorbing high strain impacts, protective armor, sports protective equipment, or crash protection devices, coatings and multiple oilier applications. ADVANTAGE - The composite material has unique architectures that can absorb significant amounts of energy from high strain rate impacts. The material has localized the damaged area and prevented crack propagation, the particulate layer has promising damping effects to accommodate both high acceleration and velocity impacts. The material provides occluded within tire inorganic crystal, significantly higher fracture toughness, hardness, energy dissipation, and damping behavior. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for making the composite material, which involves depositing different materials such that a 3-D bi-continuous network of a stiff phase and a compliant phase are generated, where depositing is done by 3-D printing, selective chemical vapor deposition, sol-gel processing, co-precipitation, or hydro-solvothermal methods; and (2) a composite material, which comprises a first hydroxyapatite (HAP) phase, and a second polymer phase, where the first phase and the second phase are substantially bi-continuous in microstructure. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of composite material. Samples (100) Stiff phase (101) Compliant phase (102) Particle form (200) Backing layer (300)
