This　study　aims　to　elucidate　the　relationship　between　process　specifically　fiber　layer,　raster　angle　and　infill　pattern　and　the　tensile　mechanical　properties　of　composite　structures.　Tensile　specimens,　fabricated　with　varying　process　parameters　using　Continuous　fiber-reinforced　thermoplastic　(CFRTP)　composites　printing　equipment,　underwent　tensile　testing　to　assess　their　strength　and　elasticity　modulus.　Additionally,　scanning　electron　microscopy　(SEM)　is　employed　to　examine　the　fracture　cross　sections　post-tensile　testing　to　determine　predominant　fracture　modes.　This　examination　also　revealed　the　internal　mechanisms　behind　these　modes　and　the　impact　of　process　parameters　on　microscopic　defects　such　as　voids,　interlayer　gaps　and　delamination.　©　2024　Taylor　&　Francis　Group,　LLC.
